Definitions
- the invention relates to a device for drilling and milling of spectacle lenses, in particular for rimless spectacles.
- the brackets and the nose bridge of a rimless glasses are usually screwed to the pre-ground lenses, so that it is necessary to bring in the form-ground lenses the corresponding holes.
- the position, the position of these holes in the respective spectacle lenses on the shape of the lenses and the nose bridge and the bracket is dependent.
- presentation glasses that are an aid to the optician to bring in the lenses to be used the corresponding holes at the desired locations.
- such platen glasses or also templates for spectacle lenses serve to determine the locations at which the spectacle lens is to be drilled or to determine the position at which a fitting or mounting part is to be fastened to the spectacle lens, for example by gluing. It is also possible to apply markings to a spectacle lens with a template, and in particular stencils are required even when eyeglass temples or nose bridges for rimless spectacles are to be attached to the spectacle lenses.
- Such templates are known in various designs, it describes the DE 44 38 634 A1 a template through which the location at which a hole is to be introduced into a spectacle lens can be determined.
- This template can be a transparent film that can be placed over an adhesive surface on the spectacle lens. The adhesive effect is designed so that on the one hand slipping of the film against the glass is excluded during the processing operations, on the other hand, the film can be easily solved even after processing from the glass.
- This type of template is difficult to handle insofar as the placement of a flat adhesive film on a curved lens surface is usually not successful at first. As the film adheres, it can not be displaced or rotated with respect to the glass, rather it must be completely detached from the glass, and finally such a film is only slightly suitable as a drilling template.
- WO 94/04957 A1 a teaching for the marking of spectacle lenses known, which also serves as a template for the edge processing of a spectacle lens.
- the gauge is disc-shaped with two mirror-symmetrical recesses and a rim of constant thickness educated. With the help of holes in the teaching spectacle lenses can be marked after their edge processing performed and the glass to be marked has been inserted into one of the wells of the teaching.
- the teaching can only be applied to spectacle lenses that can be used in one of the wells of the teaching and rest with its edge in and on the teaching.
- a template for a spectacle lens with at least one hole or mark describes the DE 197 49 631 C2 in which the template with a patch on the spectacle lens blocker against this immovable and rotationally fixed, and thus the position of the hole or the marker is to be defined relative to the lens.
- This solution also has the disadvantage that a template / a drilling aid is placed on the lens to be processed, which is used to guide drilling tools or for guiding and recording of marking elements. This does not exclude that the surfaces of the lenses are damaged by the stencils / drilling aids to be placed.
- a method for marking or drilling holes in spectacle lenses and an apparatus for performing the method is with the DE 198 04 428 A1 become known, in which the position of holes in a spectacle lens, a disc shape or a support disc scanned touching or contactless, fed the recorded data the location of the holes as polar coordinates a computer and controlling the marking or drilling by means of a CNC-controlled marker or Drilling device can be used.
- a device for drilling spectacle lenses, in particular for rimless spectacles, using a template glass in which the template glass and the lens to be drilled are used in recordings and are held on blockers in this.
- the device consists of a movable and pivotable in the X, Y direction over the common axis of rotation recording unit, a computer operatively connected to a video camera and a drilling unit.
- the template glass and the spectacle lens are arranged in the receiving unit such that the tangent planes of their surfaces form a right angle with the axis of the imaging optics of the video camera and the drilling axis of the drilling unit and the axis of the bore in the spectacle lens is perpendicular to the glass plane of the spectacle lens.
- the receptacle for the template glass and the spectacle lens are connected to each other via a fixed coupling.
- the video camera and the drilling unit are connected via a fixed coupling and arranged vertically adjustable in the device ( EP 1 437 206 B1 ).
- This device has the disadvantage that its technical implementation as a structurally and manufacturing technically feasible solution has been found to be relatively difficult. So it is z. B. barely manageable, stable and strong enough to clamp the glasses blocked on one side of the convex glass side forth for the drilling process.
- Another difficulty is the position finding of the holes to be drilled at the mirror for the bore of the mirrored mirror mirrored clamped glass, for example, for drilling the left after drilling the right-hand glass.
- the different glass surface curvatures between the platen and the glasses to be drilled which are different depending on the optical effect of the glasses to be drilled, lead to relatively large deviations of the positions of the holes.
- An additional source of error is the angle to the horizontal axis of the optical effect of the glasses. It is due to inaccuracies in the correspondence of the positioning of the blockage of platen glass and glasses to be drilled from the grinding process to the blocking for the drilling process. Here it has been shown that an alignment of the lenses alone on their ground contour does not provide the required positioning accuracy for drilling.
- a device for drilling and milling of spectacle lenses has been created in which the document glass and the spectacle lens to be drilled are clamped in one and the same receiving device and pivoted into the drilling position such that the bore to be introduced is designed such that its drilling axis According to the invention runs perpendicular to the lens plane.
- This means that the template glass and the spectacle lens to be drilled are brought into working position so that the tangent of the curvature of the spectacle lens and the axis of the drilling unit and thus of the drilling tool form a right angle.
- the inventive device is designed as a compact unit consisting of a movable and pivotable receiving unit, in which the respective document glass and the glass belonging to the glass to be processed eyeglass lenses are successively recorded, and from one with the recording unit functionally connected drilling unit with coupled video camera consists.
- the receiving device with the inserted glass or spectacle lens is movable on a stage, rotatable and rotatable about the optical axis of the lens, while the drilling unit is fixedly coupled to the video camera and arranged movable at a distance from the glass.
- both the template glass and the lens to be processed are positioned to the drilling unit that the bore to be introduced into the lens can be drilled perpendicular to the glass plane, thus the tangent of the curvature of the lens and the axis of the drilling device and thus make the axis of the introduced hole a right angle.
- EP 1 437 206 B1 because only one recording unit is required.
- the problem of possibly different, not exactly matching block positions between Exposure glass block and Bohrglasblockung is inventively achieved such that a software-technical recognition of the outer shape and position of both the glass and the spectacle lens makes it possible to perform the positioning of the glasses sufficiently accurate regardless of the positioning of the blocking.
- the fixed with the drilling unit and at a certain distance to this connected video camera projects the image of the inserted glass on a monitor.
- the video camera interacts with a computer.
- the system-based image analysis software with integrated machine control in six axes, ie three translational and with the drill spindle two rotary axes, and a tilt axis and also integrated automatic lighting control in three lighting directions is able to clamp the clamped glass with the automatically detected holes in five Axes to move so that the video camera looks perpendicular to the respectively recognized and approached hole.
- This position is stored by the software in all parameters, after which the software automatically controls the next drill hole for the exact position determination approached. After all fixing holes (drill holes) and mounting slots (cut-outs) were positioned and stored vertically positioned in this manner, can be clamped next to a glass also blocked to be drilled lens.
- the receptacle for the document glass or the spectacle lens is rotatably mounted in a lying in the optical axis of the spectacle lens Torsionsachse.
- the receiving unit is pivotable in a plane parallel to the X-axis axis of inclination.
- the device according to the invention it is possible to use the device according to the invention also to process the second spectacle lens of a spectacle to be manufactured, generally referred to as mirrored spectacle lens, ie to introduce the corresponding bores into the mirrored spectacle lens.
- the procedure is analogous to the introduction of the bore into the first spectacle lens, in that the values detected and determined via the video camera are input into a computer, where a nominal-actual comparison takes place. so that the receiving unit, in which now the mirrored spectacle lens is inserted, is positioned in such a way to the drilling unit, that the necessary bore can be introduced into the mirrored spectacle lens, this in the target-actual agreement between the document glass and the spectacle lens.
- the device according to the invention a high-precision, low-operating error and fast drilling of rimless lenses under the conditions of the optometrist trade possible, it being also advantageous that lenses, which differ from the geometric design of the template glass, if this a lower glass thickness and a lower surface curvature or a larger glass thickness and a larger Glaswölbung, can be edited.
- the glass parameters are taken into account by the software, converted into nominal position deviations and approached computer-controlled in the above-mentioned five axes.
- the conformity of the outer shape of the document glass and spectacle lens via conventional previously performed machining operations in so-called grinding machines.
- the Fig. 1 gives in a perspective view the inventive device again.
- Fig. 2 is shown their basic structure. It consists of a receiving unit 1, which is formed with a corresponding receiving and tensioning device, in which a platen 2, a spectacle lens 2 'or a mirrored spectacle lens 2 "can be used and preferably clamped by a provided blocker 2 and the spectacle lens 2 'or the mirrored spectacle lens 2 "is pivotable about a pivot axis 3, about a torsion axis 4, which passes through the center of the spectacle lens 2, 2 ⁇ rotatable and via a fixed coupling with a cross table 5, in the Axes X, Y is horizontally displaceable connected.
- a receiving unit 1 which is formed with a corresponding receiving and tensioning device, in which a platen 2, a spectacle lens 2 'or a mirrored spectacle lens 2 "can be used and preferably clamped by a provided blocker 2 and the spectacle lens 2 'or the mirrored spectacle lens 2 "is pivotable about
- a device belonging to the video camera 6 and a drilling unit 7 are interconnected by means of a fixed coupling.
- the drilling unit 7 and the video camera 6 are mounted in the device so that they can be moved in the vertical axis Z.
- the respective positions of the holes of the document glass 2 are approached, recorded and stored in succession via the multi-axis control by automatic image evaluation in the sighting point of the video camera 6.
- Fig. 3 shows another embodiment of the device according to the invention, in which the Fig. 2 known torsion axis 4 is not present. Instead of this torsion axis 4, the receiving unit 1 is equipped with a tilt axis 8, which runs parallel to the X-axis. This also makes it possible, at all necessary for drilling locations of the lens 2 'or the mirrored lens 2 "to achieve the vertical drilling position and perform all other steps as stated above.
